    The point is...being 16
  3. Hmm they only call it a hose!!, not very descriptive that eh? Ok if you have an overflow problem then the fuel needle valve in one of those carbs that are connected to the "Hose" must be passing. Can you detach the "Hose" from the carbs? and then you will see which of the carbs has a problem.
  4. I'm stumped too at the moment, i dont think they are overflow pipes, you wouldnt expect petrol to be overflowing somewhere high up on the bike, that might be dangerous fire hazard, so they could be breathers which are there to keep the float bowls at atmospheric pressure. Have you got the rest of the info for that drawing, the bit that says what the parts actually are?
  5. I have no experience of this bike but from what i understand you said is that only one carb is overflowing, are they overflow pipes in which case the dont connect to anything at the other end?
  6. Its a four cylinder isnt it? How many carbs are overflowing, surely not all of them at once?
  7. Hi Alan, assuming its a mikuni VM carburettor, im thinking the pilot jet bypass hole is blocked (If it has one) its a small hole in the bottom of the venturi, allows fuel through the pilot jet to exit behind the throttle slide when shut, also worth a look at the air jet. A rough guide to this working or not is to adjust the mixture screw, it should have a noticeable affect on engine speed at tickover, if blocked you will see no affect.

    Quick Hello

    Hi Paul and welcome, ive been beating the traffic for a long time now, soon be getting the pushbike out again!!
  9. I dont get it either, its a rwo stroke motor, the warning lamp on these is usually to say put some two stroke oil in the oil tank behind the side panel. I didnt know they had a light to say put oil in the engine! seems a bit daft to me as its only there to lube the gearbox and doesnt actually get used up, Unlike the two stroke oil which does get used up. I suggest you read your owners manual.

    I doubt you will get any positive answers to this due to no one ever tried, for what its worth and its an educated guess,,,no!...sorry
  11. Dont rightly know myself either but i would think that if in uk then unless you pass your test you cannot de restrict it because learners have to be on 12 BHP (Or whatever) and if in Portugal i dont know it depends what learners use there...dont know...Not my strong point, Goff's good with learner issues i think
  12. Will it tick over on starter jet, like peatandyman said, If it will then it looks like a blocked pilot jet in the carb.
  13. Would i be right in thinking it starts ok on starter jet or choke ? (whichever is fitted) and then dies when you turn that off unless you keep the revs up?

    Good to hear Steve, welcome to the forum, nice bike too!
  15. Hi mop head, not familiar with your specific bike, but is that light telling you to put some two stroke oil in the tank, ...I think so. And if you have been topping up the gearbox oil make sure it is only half way in the window or it will be over full!!
  16. Some you can and some you can't have a look at the stator plate mountings see if the holes are slotted.
  17. I would if i could but manuals for this bike are non existent, do a search on the forum, theres been posts about this bike manual.
  18. Caustic is a very good way to clean carbon yes, only use it on steel exhausts, not on anything aluminium. Wear gloves and goggles too because you will get serious burns if you get any on you.
  19. Soldering floats up can sometimes add weight and therefore affect buoyancy of the float this then leads to higher fuel level in the bowl.is the problem only on the cylinder with the repaired carb?
  20. Yes you can, ask them to fit it if you dont know what youre doing.
